ABSTRACT: When dealing with open evaporative cooling water systems, there is two performance parameters of primary concern, corrosion and fouling. On-line monitoring of either would appear to be independent. By dividing the various forms of corrosion and fouling into subsets, interdependency can be established. This analysis, combined with the real-time dynamics of the cooling system, provides a link between Key Performance Indicators (KPI) and Key Operating Indicators (KOI). The real-time, linkage can be harnessed to stepwise adjustments of controlled parameters such as blowdown, pH, oxidant, non-oxidizing biocides, dispersants, deposit control and corrosion control additives in order to maintain corrosion and fouling within their respective user defined control ranges.
